Step 1
Locate one RJ-11 to RJ-11 cable for each
device to directly connect to the two FXS
Cisco uBR924 cable access router VoIP
ports if voice is supported.
Step 2
Connect one end of the cable to one of the
Phone ports (labeled V1+V2 and V2) at
the rear of the router. Press the cable
firmly into the receptacle.
Step 3
Connect the other end to the telephone,
fax device, or adapter as appropriate.
Note: Use only a telephone with a pushbutton dial
set. Fax devices and fax/modem cards can be used in
Cisco IOS Release 12.0(5)T and higher; however, the
data mode of the fax/modem card cannot. Contact
your network management, provisioning or
operations team to determine if fax/modem cards are
supported across your VoIP network.

Caution
Multiple telephones or fax
devices can be connected to the two VoIP
telephone lines, provided the sum of the
REN of all devices on the line does not
exceed five. A two-line telephone can be
plugged into the V1+V2 rear connector of
the router using a single cable if the cable
has four wires.
Step 4
Repeat steps 2 and 3 for other devices to
connect to the second VoIP telephone line.
Warning
Install equipment using an
acceptable method of connection per your
country. This equipment contains a ring
signal generator (ringer), which is a source
of hazardous voltage. Do not touch the
RJ-11 (phone) port wires (conductors), the
conductors of a cable connected to the
RJ-11 port, or the associated circuit board
when the ringer is active.
